We investigate the impact of polarization-dependent loss (PDL) on the\nlinearly coded digital phase conjugation (DPC) techniques in coherent optical\northogonal frequency division multiplexing (CO-OFDM) superchannel systems. We\nconsider two DPC approaches: one uses orthogonal polarizations to transmit the\nlinearly coded signal and its phase conjugate, while the other uses two\northogonal time slots of the same polarization. We compare the performances of\nthese DPC approaches by considering both aligned- and statistical-PDL models.\nThe investigation with aligned-PDL model indicates that the latter approach is\nmore tolerant to PDL-induced distortions when compared to the former.\nFurthermore, the study using statistical-PDL model shows that the outage\nprobability of the latter approach tends to zero at a root mean square PDL\nvalue of 3.6 dB. On the other hand, the former shows an outage probability of\n0.63 for the same PDL value.\n
